Performance, economy and price, you can't have all three, there's always a compromise. The difficulty comes in deciding where to compromise and figuring out which is best in the long run. For example lets budget £3,000 for a car, it needs four wheels and preferably four seats.
Compromising performance gets you a 2002 Ford Fiesta 1.4 Diesel, 64mpg and 68bhp. Compromising economy gets you a 1996 Skyline 2.5 Turbo, around 20mpg and over 250bhp. Compromising price gets you a 2006 Alpina D3 2.0 Diesel, 47.9mpg and 200bhp but for three times the budget at £9,000.
Personally I wouldn't drive the Fiesta, couldn't afford to run the Skyline or buy the Alpina but they illustrate the point nicely. I've been looking at the total cost of ownership over a few years for a variety of cars that I've been considering. What I've found is that it's cheaper over three years to buy a less economical car than to pay the premium for the "economical performance cars". It's food for thought so now I just have to make a decision.
