XC90 Used purchase / tip needed

Hello dear forum community, I’m looking for an XC90 for a good price / performance ratio. Now I’ve seen an offer, but ask me … is the price normal? A 12/06, 1st hand, 7-seater with 88,000 km for a good 23.000€. Strange is, Grantie possible +650€, but is a dealer. 4.5 hours driving time (one distance) want to be well thought out. For just to look a little bit far away! Or should you better buy in the vicinity if problems with the vehicle occur? A “about” comparison offer 02/06, 1st hand, 7-seater with 60,000 km for a good 28,000€ with the difference of almost 5,000€! My dealer on site is always something very expensive than others! What experiences did you have?
