Thanks guys.
Well got the Wagon (PM35 350RX) and had proper drive on way home.
Very impressed and the 5 speed auto is way better behaved on the big hills. It came with one of those aftermarket English owners manuals, supposedly only 100kg heavier than the 250RS but carries it better.
Prob the 17 inch wheels make a difference, other wagon had 16's. This one has 3 brands of mismatched and 2 worn tyres and still drives beautiful and straight, will sort new tyres soon.
Has Pioneer Carrozia HDD radio, pretty much sussed out how it all works, find the reversing camera bit gimmicky and no substitute for knowing the size and feel of your car with the wing mirrors instead.
