I guess the point people are trying to make is low miles does not necessarily equal a good car, but that also the opposite can be true.
Maserati may be a fantastic high performance car, but the market is less supportive than other comparators; sadly as a result residuals are lower. In turn that results in people being less willing to service the car as per the schedule as the return is just not there.
My own car in point has had more spent on maintenance over its life than it is worth today and at higher 50s is seen by many as being high miles (3.5k pa).
Conversely there are lots of very low miles cars of the same age with just 4 or 5 services and 20k on the clocks... which is the better option? Eye of the beholden.
The final point is that a low miles car will only retain its value above a higher used one if it is not used... which kind of defeats the point as no modern one gains more in value than it costs to run and maintain.
Even I can be guilty of sniffing out the fewest owner, lowest mileage car.
The thing about cars with mileage, they often have had to have been repaired and if not, the parts have just coped well with regular usage. Service history isn't worth the paper it's printed on. Here is an example, I purchased Maserati Granturismo 2008 with "FSH". As it turns out, anyone can make receipts
Also, my other motor, a Renault Megane RS Cup. If you arent sure what the CUP is, they are made in exceptionally small numbers, a homologation within a homologation of the RS racing series.
The car was advertised with no mention of service history. Upon investigation, the car was owned by a chap who works for Cooksport, a business which coincidentally races megane Cups. The car didn't want for anything, the book however had never been stamped and the paperwork was very limited. Everything that needed doing had been replaced and parts were a plenty. I bought the car for a snip of its market value had cooksport had stamped the book each time they dropped the oil and provided a bunch of paperwork...
Now compare this to a car that has had 14 "dealer stamps" for the same 80k miles... The car repaired to a budget (often), the services carried out based on a service indicator (assuming they have actually been done) but mr or mrs new owner can feel happy they have a book of stamps. Now i collect stamps, just not once made with smash and blot ink
Whilst this might be a type of fraud, its very simple to buy a stamp off of an internet auction site, made out with any name you like. You can also easily make copy invoices using a PDF editor. I'm sure this happens much more than anyone would like to think.
Flash car dealers are just used car salespeople in flashy suits.
Main dealers are glorified used car dealers.
Used car sales are what they say on the tin,
used cars!
Expect to be buying someone elses problem and then nothing will be too concerning.
