OK, quick update. Fitted matching Toyos on the front and the car handling has been much better since, and no more traction control issues. Also had it serviced (incl new platinum tipped spark plugs as apparently they're due at 54k) and new front discs and pads. £1k. Excellent, I'm glad I've spent that, the cash was only getting in the way sitting in the bank
So that just leaves the minor issue of the 5th/6th synchro (est £1k), the clutch that's on the way out and might as well be done at the same time as the synchro (£700, although will save labour if done along with synchro), the so-called minor scuff that will cost about £250 to get a good job done on and the other minor issue that the car broke down on me while driving home from work on Friday night - sudden loss of power while foot to the floor at about 4k rpm in 2nd followed by running rough, will start but refuses to rev or tickover.
I saved for 3 years to get this car. It's halved in value over 12 months, it's costing me a fortune and gradually ruining me. I have never hated a car more.
GGRRRR!!
Apart from that, everything's peachy!
