It depends on all manner of things, and if any of them are bad then I disagree that it will be more reliable. Many new cars with few miles are unreliable after all (less so than 20 years ago, but hey, this is a 20 year old car we're talking about). ultimately 16,000 miles is more than ample to completely wreck a car if it's sufficiently abused. I'm not suggesting that this one is likely to have been, but it could inadvertently have been treated less than optimally all the same. Questions relevant to its likely condition and reliability:
- How has it been stored? Clearly it has been in storage for the vast majority of its life, even if storage means regular short periods of 2 or 3 weeks between outings?
- It's in Scotland. Has it been there all its life? Near the coast? If so it will very likely be rusty. Triply so if the answer to the point above is anything other than "in a climate controlled garage" and/or if it was regularly parked without being cleaned after winter use. I grew up there so I definitely own that knowledge.
- Has it been serviced regularly or was it owned by someone who thought no miles meant no need for maintenance?
- When it was used, how was it used? Loads of short trips, good long runs, once a year to the Nordschleife for a serious ragging?
