The most-searched UK budget is £15k to £30k. A Nissan keeps topping it.

Across the last forty searches run through the finder, one combination appears more than any other: UK market, £15,000 to £30,000, right-hand drive required, and "hasn't run yet (early in cycle)" ticked as a criterion. Variations on it, £20,000 to £45,000 with a manual gearbox and usable daily, make up most of the rest. This is the centre of gravity for UK enthusiast demand right now.

The interesting part is what actually scores highest against that brief. It is not the BMW M3 E46, which is the single most recommended car in the whole library at eight appearances. It is the Nissan 370Z.

What the scores say

Four separate 370Z entries sit in the library, and every one of them lands in the top tier of the £15k to £30k band with an early-cycle classification:

• 370Z Nismo manual (2014 to 2020), score 80.4, price band £20,000 to £30,000
• 370Z manual coupe, UK RHD (2009 to 2020), score 79.1, price band £14,000 to £26,000
• 370Z manual coupé, late facelift preferred, score 79.1, price band £15,000 to £25,000
• 370Z manual coupe (2009 to 2020), score 76.5, price band £18,000 to £28,000

The thesis behind those numbers is consistent across all four runs. The 370Z is the last naturally aspirated Z-car, with a 3.7 litre VQ37 V6, hydraulic steering, rear drive and a six-speed manual. Production stopped in 2020 and the replacement is turbocharged, which fixes the 370Z as the end of a line. UK manual cars are plentiful in RHD, which matters given how often that criterion appears in the searches. And unlike the S2000 or the E46, it has not yet been picked over by collectors.

The 350Z sits a rung lower, and the data explains why

The obvious cheaper alternative scores noticeably worse. The 350Z HR GT manual coupe (2007 to 2009) comes in at 65.9 in an £11,000 to £18,000 band, and the earlier 350Z manual coupe at 54.3 across £8,000 to £18,000. The gap is not about the driving. It is that the 350Z was built in far greater numbers, took a much harder beating from the modifying and drifting scene, and lacks the clean "last of its kind" story that the 370Z owns outright. If you want the cheapest way into a naturally aspirated Z, the late HR 350Z is the pick. If you want the version the scoring model prefers, it is the 370Z.

What it is up against in the same money

The 370Z is not alone at the top of this band. The Porsche Cayman S 987.2 scores 79.2 at £19,000 to £30,000, the 987.2 Cayman 2.9 manual scores 76.6 at £16,000 to £28,000, and the Lotus Elise S2 111R scores 73.7 at £18,000 to £32,000. All three are early cycle. The Honda S2000 UK AP1 facelift, by contrast, scores 59 and is classified mid-cycle, which is the model saying the S2000 has already had a good part of its run.

Read that group together and the pattern is clear. The band rewards naturally aspirated, manual, rear-drive cars from the late 2000s that have not yet been reclassified as collectibles. Browse the full set in under £25k and early in the cycle.

The honest case against

Confidence on the 370Z entries runs between 0.61 and 0.70, which is moderate rather than strong. The reasons are worth taking seriously. Production volume was high, so scarcity is thin. There is no motorsport pedigree or badge prestige to lean on, which is exactly what has driven Porsche and BMW values. A large share of surviving cars have been modified, tracked or neglected, so condition spread is wide and the good ones need finding. And a stable market can stay stable for a long time. Early in the cycle is a description of where prices sit, not a promise that they move.

What the data does support is narrower and more useful: a usable, reliable, right-hand drive, naturally aspirated manual coupe that costs less today than it did five years ago, in the exact budget band most UK enthusiasts are searching. That is a reasonable place to start looking, not a reason to buy blind.
