The K series engine in my Rover 420GSi was awesome! Really revvy little unit and pretty powerful when you worked the box. In fact, comparing it to, say, a Ford Mondeo 2ltr of the same period its a really entertaining car. Same amount of power as the ford, but a smaller and lighter car. Only downside is the decent performance is reflected in the insurance, weighing in at group 14.
Sure, the chassis and body is dated these days, but when they were released in the 90's they were quite handsome cars, with a quality interior and decent performance.
Its just a shame that they continued trying to sell the 25 and 45's as modern cars. Up against the focus they dont really stand a chance, whereas the 75 is a lovely cars and can be picked up as real bargains now.
I havent seen the new TF, but it has a hell of a lot to live up to its its taking that name! Good luck to them anyway.
