So I'm bored and jetlagged and was awake at 5am.
After several of you have been mentioning about factoring mileage in I was trying to think of the best way to do this.
SteveH72 had a go by using pence per mile, and although that makes Coupe's look even better (which they are) it is going at it the wrong way round as of course, So I thought you have to multiply the price with the mileage, and throw in a few other factors to get figures that can be applied to Roadsters and Coupes fairly.
(Still awake at the back?) :?
I messed around for a while trying to combine mileages and prices to try and get a Mileage x = price Y formula, but basically couldn't without assuming a figure on mileage affecting price ( I guessed at £1200 per 10k which seemed to work out somewhere near what we might expect)
However I'd now also have to assume a starting price for a 10k car and realised that I was on a hiding to nothing, as I was assuming a starting point and an increment which both may or may not be true.
So I chucked my toys out of the pram, started again and just chucked all the data in to an excel chart and it came out like this....
I think it shows that -
a) Coupes are more mileage sensitive - possibly because of a perceived opportunity to keep as long term investments
b) The asking price difference for similar mileage coupes and roadsters is in the £3-5000 range.
This - as someone stated earlier does not take condition, service history, colour, options in to account at all.
Not at all scientific, but then again, what is on here
not sure why you'd have a roof to start with on a sports car... Good thread

By the seaside...
