I absolutely love my 75 tourer and, with the major exception of head gasket failure, its reliability has been supremely reliable.
Parts are reasonably priced (its worth looking for minor bits from BMWs and Freelanders of the same era (early 2000s 3 and 5 series) as many are the same. With production having restarted in China the situation is getting easier.
I also recommend that anyone with one joins mg-rover.org as this forum has the answer to everything.
The car is a little underpowered in 1.8 auto form but is supremely comfortable and a wonderful place to be - the interior is amazing if, perhaps not as spacious as it should be for the size of car.
I would recommend one to anyone who is looking to buy in this category. If you want something a little sportier I suggest you look at the very similar but sportier MG ZT-T but I prefered the laid back nature of the Rover.
The rover 75 is a good car, it is ok to drive, has plenty of space and is fairly reliable but there are some problems i have found from owning one.
I have a Rover 75 1.8 litre estate and it just doesn't have enough power. When driving it normally its ok just a little slugish but when you are towing with it you can feel that its just not got enough power when you need it. My advice is that if you are going to buy one and you are going to be towing with it buy a model with a bigger engine. Apart from the power issue it is great and when crusing you can hardly tell there is a trailer on the back.
The other main issue i have had with the car is the fact that the parts for all rovers and now becoming very expensive and harder to find. Things that should cost twenty, thirty pounds are now heading up to the hundred pound mark.
My advice is if you want one buy one but know that the parts for this car will only end up going up.
The Rover 1.8 club (automatic)has too many faults, i was going to buy one earlier this year but was advised not too by a good friend of mine, let me takes you through the faults that have been found on this overated vehicle. 1: Cam cover gaskets leaking due to torque relaxation in other words the bolts on the Cam Cover are always coming loose. 2: Head Gasket always blowing, causing oil and water to mix. this would be down to poor gasket design and cylinder heads warping. 3: Rear shock absorbers creaking. this is due to a manufacturing problem as Rover are now fitting modified shocks on all new cars. 4: Rear doors stick and are difficult to open. Door latch pivot point sticking. 5: Cam Seals leaking. This causes cambelt oil contamination which can weaken and lessen life of belt unless changed. 6: Water ingress. Drain channels in bulk head are getting blocked and water is filling scuttle panel, then via heater into passenger footwell. Odd Cases: 1: Cental locking operates when the volume control is adjusted via the steering wheel controls. 2: MIL (maulfunction indicator lamp) coming on for no reason. 3: Coolent loss was a common problem on previous k series engines until modified inlet manifold gasket fitted. Overall this car is very underpowered due to 1800cc engine and automatic cvt box in a very heavy car. Although this is bad report the Rover 75 has good points due to BMW design.
