Hmm.
Why did he fit a new water pump? Did it actually overheat?
The price of cherokees does vary greatly with time of year they are entering the period where the start climbing...
£1,500 is quite a lot. Yes some people ask up to 2k for them and it is a lot of vehicle for your money and still loads better value than a Disco so ppl pay it.
Si paid £800 for a 4.0L Limited from a dealer ith full Jeep service history and about 65k on the clock iirc. Absolutely mint except the door glass rubbers are looking very tired and it needed a t-cut. The rear leaf springs were sagging too (common problem). (as an FYI, the diesel ones sit a good 1-1.5 inches higher).
If you got a 4.0L for half the price it would pay for the difference in fuel cost over almost a year i guess?
I thought the days of finding good ones for £500 ended a year ago but they do turn up from time to time.
I still think he wants top dollar, but if he's replaced so much on it and it's now a really good one, maybe it's worth paying it...
