well, expectations kene manage.... thats all i can say :smokin. Have to sabar cari kereta, most units being sold cheaply wont be perfect, they will have their flaws. Best advice i can give you is ask... ask for everything you can about the car, pictures and all that. Looking at cars that old, its going to take a while before you find a nice unit... min took me about 1-2 years i think?
about the warming up bit, if it was a very cold day or its possible the fella either messed with the idel or maybe added some 'stuff' into the car....
