Rear exhaust had to be replaced after 18 months.
Right brake bulb keeps going.
Mode button on radio has fallen off.
Oddment cubby on drivers side has come away from the dash.
Mechanically sound and reliable but parts of the interior trim are flimsy.
Comfortable on the motorway at 90mph.
My Rover 618Si has a faulty driver's side electric window. The window falls out when used. Rover can modify the seals on the window for a measly £250. They have a kit as it is a common fault according to the service manager.
Try using some talcum powder around the seals (honestly), it stops the window from sticking to the seal.
Try rubber lubricant from Halfords. It comes in a yellow can and costs under a fiver.
Lower each window and craefully squirt this slippery stuff along the running channels.
Raise and lower each window about 5 times.
Repeat this process one more time and voila! smooth, quiet window operation.
DO NOT USE WD40 it will wreck your rubber...

I had this problem too, and it cost me £150 to get put right at a Rover dealer. However, that is the only thing that has gone wrong on my 3 year old 2.0 SLi. We thought of changing it this year, but, frankly, couldn't find as nice a car without spending lots of dosh. It's a good looking, comfortable, acceptably powerful car that is hugely under-rated. The replacement 75 is gorgeous inside, but looks like old man transport from the outside. What a shame they didn't just refine the 600 interior.
