I`ve found the car to be reasonably easy to service
The 2.0 & 2.2 ltr 16V engines are quite rev happy & if serviced correctly will be reliable.
The mig is a heavy car & you ain`t gonna set any 0 to 60 record times
Fuel consumption around town & in the winter I`m gettin about 22 MPG
But compared to a Euro box, my car is a pleasure to drive.
I`ve seen some new members throw wads of cash at cars & if they don`t get instant results; probably get pee`d off & are never heard of again
Only you can decide, if after getting the engine sorted; do you then have enough in the kitty to sort any additional work that crops up.
Be prepared to stump up for main dealer prices on cam & crank sensors.
After market parts don`t last long & some members go around in circles chasing engine & electrical gremlins of their own making; cos they`re using crap knock-off junk from flee-Bay
Best of luck
let us know how you get on.
