2006 Toyota Corolla e12 t3

Field car: Quoted around 800€ to fix rust on it Mx5 angel wheels on it in poor condition Tires are aged, minor cracks but good tread Egr valve stuck shut, so engine light on. NO LOGBOOK, TAX OR NCT Drives okay, but low on power Straight piped from midsection back, not too loud, turbo noise Want to buy a better car, but would swap for something with NCT Been offered 350€ hoping for a little more but will accept that Starts right up, but does vibrate a little past 100km/h Discs minor warped on front and handbreak on bck left not working. Just want to get rid of it, will leave it up for at last a week before accepting offers unless its a good one
