Quality costs money.
The car has low miles and is very clean. Great!
It's probably a one owner car.
So how does one justify paying a premium for perceived quality?
Does the paint look like the car was garaged for most of its (non-driven) lifetime?
Does the seller have a complete maintenance history that you can review?
Clean CarFax?
Finally, what are YOUR intentions? Will you keep this car for say, five years? Longer? The longer you realistically expect to keep such a car the easier it is to justify paying a premium for quality.
The CD model is cute and a nice car if you don't need to use its back seat and don't need full headroom. Nice car for one or two, otherwise a sedan is preferable. Same power train in each.
I use this mathematical formula to judge a car vs. similar cars (insert your own values):
( equation assumes the engine & transmission have a 275,000 mile useful life before overhaul )
Cost per remaining mile = [ (Cost - scrap) / (275,000 - miles done) ]
[(6000 - 1000)
/ (275000 - 100000) ] = .02857 / mile
Insurance companies will immediately "total" an old car, regardless of its condition. So its up to you to avoid being "rolled" by being able to justify its premium value with records, pictures, comparable sales of similar mileage cars etc. They'll pay if a premium is warranted. Keep this in mind if you buy it.
