Hi and Welcome to LOC Chrisy Bhoy :)
Its worth doing your homework on the LS ;)
There are good and bad condition cars for around the money you say.
The best piece of mind would be to spend the price of a MOT and take the car for one,tell the garage that the cars yours and your selling it :winky:
They will have a GOOD look over the car as they wont want any come backs from the new owner if you sale it on.That way you will have a idea on how much the parts might cost if you have to replace anything if it fails.
Suspension parts are they expensive parts on the car if your looking at keeping the car for a few years.
If your looking at just running the car for a year or less and bin it if it fails its next MOT and dont mind losing a few quid then as long as its got a long MOT then its still cheap motoring.
£1200 is alot of car for the money,but not if you have to spend anything on it.The LS is a Hard car to sale on because not many people want the running costs.
My Advice is to Hangle Hard when buying B)
Good Luck with the car if you do go on to buy one.
Cheers..
