well for 300 quid its worth every penny..... if you can be bothered to sort out all the wiring issues, get the car rolling again, go through the whole lot with a fine tooth comb, and put right all what is wrong with it. The worst thing about it all is that the owner seems very vague on what it is he actually has, and you can clearly see it has been chopped and changed alot.
Dont get me wrong from the outside it does look very nice and tempting, and it is the best engine (the 2.0 16v) and with it being chipped (apparently) then thats a good start, but the fact that the engine doesn't start is a bit concerning. as for the price like i said its very good, but if you kept looking you may find a fully working 155 in a better condition and road worthy for anywhere between 500 - 1000, dont pay any more than that as you wont get any money back for them. Its just one of those things, its a love affair and nothing more.
If your good with electrics, mechanically minded and happy to spend some money then its not a bad purchase.
