The Nissan 350Z and 370Z represent two generations of Z car excellence. Both offer rear-wheel-drive V6 thrills at accessible prices, but they're different cars with distinct characters. If you're shopping for a used Z, understanding these differences will help you make the right choice.
Let's break down everything that matters: performance, reliability, driving experience, and total cost of ownership.

Engine: VQ35HR vs VQ37VHR
Both engines belong to Nissan's legendary VQ family, but they have distinct personalities.
The 350Z's VQ35HR
Introduced in 2007, the "HR" (High Response/High Revolution) version of the 3.5L addressed every weakness of the earlier DE engine. It features:
- Revised intake manifold and exhaust for better breathing
- Improved oil control virtually eliminating consumption issues
- Stronger internals capable of revving to 7,500 rpm
- More linear power delivery throughout the rev range
The VQ35HR feels eager and responsive. It pulls cleanly from 3,000 rpm all the way to redline without any flat spots.
The 370Z's VQ37VHR
The 3.7L engine builds on the HR platform with additional displacement and refinement:
- 200cc more displacement from a larger bore
- VVEL (Variable Valve Event and Lift) for precise throttle response
- 26 more horsepower with similar fuel economy
- Even smoother power delivery
The VQ37 feels more sophisticated. Throttle response is instantaneous thanks to VVEL, and there's noticeably more midrange punch for everyday driving.
Engine Verdict
Both engines are excellent and reliable. The VQ37 has more power and better throttle response, but the VQ35HR is no slouch. The difference in daily driving is noticeable but not dramatic.
Driving Dynamics
Chassis and Handling
The 370Z sits on a shorter wheelbase (100.4" vs 104.3"), making it feel more agile and eager to rotate. The suspension geometry was revised for sharper turn-in and better mid-corner balance.
The 350Z has a slightly softer, more comfortable character. Its longer wheelbase provides more stability at highway speeds and a more relaxed feel during normal driving. Many consider it the better grand tourer.
Steering Feel
Both cars use hydraulic power steering, which enthusiasts appreciate. The 370Z's steering is slightly quicker (2.6 turns lock-to-lock vs 2.7) with a more direct feel. The 350Z's steering is a bit more relaxed but still provides good feedback.
Transmission
The 6-speed manual in the 370Z features SynchroRev Match—automatic rev-matching during downshifts. Purists can turn it off, but it makes for impressively smooth heel-toe shifts. The 350Z's manual is more traditional but well-suited to its character.
For automatic buyers, the 370Z's 7-speed is a significant upgrade over the 350Z's 5-speed, with quicker shifts and better fuel economy.
Handling Verdict
The 370Z is objectively sharper and more athletic. The 350Z is slightly more relaxed and comfortable. If you prioritize corner-carving, choose the 370Z. If you want a more balanced grand touring experience, the 350Z may suit you better.
Reliability Comparison
Both cars have proven to be reliable sports cars, but there are differences:
350Z Reliability (2007-2008 HR)
- VQ35HR is very reliable with proper maintenance
- Timing chain guides may wear at very high mileage (180k+)
- Window regulator failures are common but cheap to fix
- Clutch/flywheel replacement needed around 80-100k miles
- Parts are widely available and affordable
370Z Reliability
- VQ37VHR is equally reliable
- Galley gasket issue on 2009-2014 models (important to research)
- CSC (Concentric Slave Cylinder) failure on manual models
- Similar window regulator issues as 350Z
- Parts are slightly more expensive
Important: 370Z Galley Gasket
The 2009-2014 370Z has a known oil galley gasket issue that can cause catastrophic engine failure. Nissan redesigned the gaskets in 2015. If buying a 2009-2014, check if this has been addressed. The repair is ~$2,000-3,000 for peace of mind.
Cost of Ownership
Purchase Price (2024 Market)
| Model | Fair Condition | Good Condition | Excellent |
|---|---|---|---|
| 350Z (2007-2008) | $12,000 | $16,000 | $22,000+ |
| 370Z (2009-2014) | $15,000 | $20,000 | $26,000+ |
| 370Z (2015-2020) | $20,000 | $26,000 | $32,000+ |
Insurance
Insurance costs are comparable between the two, though the 370Z may be slightly higher due to its newer model years and higher value. Expect to pay $100-200/month depending on your location, age, and driving record.
Maintenance Costs
Routine maintenance is similar for both:
- Oil change: $50-80 (DIY) / $80-120 (shop)
- Brake pads (set): $100-300 depending on quality
- Tires: $600-1,200 for a set (staggered sizes)
- Clutch replacement: $1,200-2,000
The 350Z has a slight advantage in parts pricing due to being older, but the difference is minimal for most components.
Fuel Economy
Neither car is economical, but they're acceptable for sports cars:
- 350Z: 17 city / 24 highway (manual)
- 370Z: 18 city / 26 highway (manual)
Interior and Comfort
The 370Z has a more modern interior with:
- Updated gauge cluster with larger tachometer
- Better infotainment options (later models)
- Slightly improved material quality
- Similar seat comfort and driving position
That said, the 350Z's interior has aged reasonably well and remains functional. Neither car is particularly luxurious—they're focused sports cars.
Which Should You Buy?
Choose the 350Z If:
• Budget is a primary concern
• You want a more relaxed grand touring character
• You prefer the 350Z's styling (subjective)
• You value slightly lower parts costs
• You want to avoid the galley gasket concern entirely
Choose the 370Z If:
• You want maximum performance
• Sharper handling is a priority
• You prefer the more aggressive styling
• SynchroRev Match appeals to you
• You want a newer car with more modern features
• You're buying a 2015+ model (no galley gasket worry)
The Bottom Line
Both the 350Z and 370Z are fantastic sports cars that deliver genuine driving enjoyment. The 370Z is objectively better in most measurable ways—more power, sharper handling, more features—but the 350Z remains an excellent choice, especially for budget-conscious buyers.
The best advice? Drive both if you can. These cars have different characters, and your preference may surprise you. Some drivers prefer the 350Z's slightly softer, more relaxed nature. Others immediately connect with the 370Z's sharper responses.
Either way, you'll end up with a reliable, fun-to-drive sports car with one of the best naturally-aspirated V6 engines ever made.
