Very comfy car, clutch foot rest is a welcome standard feature!
Nice airy, light cabin, easy to use controls, decent quality plastics and generally screwed together quite well. Rear leg room not too bad unless you're a complete giant, but if your distinctly average like me (5'11"), the rear leg room is OK. Front seats fantastically comfortable and adjustable in just about every direction! decent lumbar support.
Ride is firm, but still supple enough not to rattle your fillings!
Handling is quite good for a car of it's size and stature. Plenty of steering feedback, it's a nicely communicative car to drive.
Performance is more than adequate, it's surprised quite a few drivers out there who assumed they'd leave it for dead! Yes, I know, childish, but you have to use the performance now and then! ;-)
I've heard tyre wear, gearbox, drive-shaft and head gasket failure and premature wear fables told a-plenty, at the end of the day, if you abuse a car, neglect it and generally use it hard, don't complain if it breaks down and costs you dearly to rectify any problems which it develops.
This will happen to any car if the above treatment is applied, so the ti is not fairly criticised 99% of the time. I see a lot of people complain the gearbox crunches into reverse, it has no syncro on reverse, read the manual, it does tell you to dip the clutch and pause before selecting reverse to ensure the gearbox doesn't crunch! (or select a forward gear before reverse).
Standard Rover alarm and immobiliser is quite a sophisticated setup with rolling code and passive arm function as far as I recall.
Despite all the negativity about Rover, I'm still to buy an unreliable one, my current 620ti being no exception to my findings with the breed so far.
Look lots before buying, plenty of used and abused examples out there for too much money. High miles are not a problem, just find one with good service history or at least decent evidence of self service (recorded mileage, date of service, full or interval service, receipts for parts and fluids etc).
Major service costs no worse than for any other medium-large saloon of it's class, though oil changes need to be at 6000 mile intervals and quality lubricant must be used.
Insurance costs not as bad as some would have you believe, current insurance costs for a 28 yr old male living in the Staffordshire area, third party fire and theft £360.
Fuel costs not too bad at all, it will return between 30 to 32 mpg around town, and is capable of doing 39 to 40 mpg on a run, if you're very careful anyway! not bad for a car which weighs 1365kg and has a 2.0 turbo petrol engine!
Tip, if you have just bought one, get it serviced, inlcuding changing the gearbox oil (makes sure the oil is the correct grade for the torsen type 'box fitted to this model), and make sure the coolant is changed and topped up to the correct level with the correct coolant ratio.
Having the brake fluid completely renewed is also a good idea, but this isn't specific to these cars, it just makes good sense whatever car you buy!
In all, a nice, well presented car with very solid performance, looks more expensive than it is, and quite in-expensive to buy!
