Good point about other components.
I've recently been looking for a cheap (but decent and practical) stopgap daily driver and settled on a PT Cruiser (had one before and liked it a lot). Not an obvious comparison to choosing Crossfires you might think but - for obvious reasons of economy, high mileage diesels (even older ones) are quite expensive compared to often newer lower mileage petrol cars, so I decided on the latter because, even though diesels use less juice and tolerate the big mileages better than petrols, many of the other components wear out at the same rate, regardless of which lump is under the bonnet - and it's not just running gear but seats and other interior parts.
OK, everything can be fixed (for a price) - and some folks will say I'm daft for worrying about cosmetics - but you don't want to put up with tatty (and sometimes smelly) surroundings every time you get into the car - spoils the experience.
Lower miles often mean a better experience all round, so it can be well worth spending that little bit more - doesn't have to be a lot - just keep looking!
