Thanks Peter! As it happens, i picked up the wee beastie today :
Only 78k and one owner from new, fitted LPG conversion, full service history (mostly Jag dealer then indy), drove really well and managed to negotiate a bit off the price for the common heater blowing hot problem because the heater valve isn't closing. Allegedly the heater valve has already been changed so it points to the ECU or control panel i believe.
As you can see, it's near enough immaculate inside and out although i've found a couple of trim niggles that need fixing, one is the left door mirror cover and the other is the sill trim in the boot which appears to have been damaged during the LPG tank installation.
Also thought i had a piece of loose trim on the dash until i touched it to silence it on the way home and discovered it was in fact a coin tray with about £1.40 in 20p pieces! Only a small victory but a win is a win! 😉 😄
