I have two Hdi RCZs in my garage and they are amazing don't let the milage put you off as they say these engines are bullet proof if you get one with full service history then it is more likely to have been looked after both of ours have over 60,000 miles on but they run and sound like a new car... Wish they still made them now as I would buy a Hdi in a heart beat..
Try to get Xenon lights, leather seats, sat nav... And check out the jacking points for damage.. And the middle brake lights for LEDs not working...
