Low mileage car @ 70K!!!
You should be looking for one with 35-40k on it if you want low mileage.
My 38K 54 plate UK Ginger ( with lmgt4'S) cost 8'5K last November and prices have tumbled since.
Ok it had 4 previous owners and a service history with independents since its warranty ran out but the previous owner was a merc mechanic who had dealt with every niggle no matter how small.
Took me 4 months to find, just have a bit of patience and be prepared to travel a few hundred miles to see a few.
Don't believe the bloke who says its mint, ask specific questions on the phone, Is the bolster worn on the drivers seat, are there any car park dings, are the tyres new, is there any rust etc...etc....
Above all have patience
Drive a few ( Even overpriced ones at dealers so you get a feel for what's right, how it should turn and brake. etc)
And have patience.
Oh & by the way.................
have patience
