Think Triumph 2000 with TR5 engine, which made this Britain’s first family car to be fitted with fuel injection. After little over a year it got the MkII bodyshell, but neither had the best reputation for reliability – mostly fuel injection problems, though you can expect those to have been sorted out by now. This led Triumph back to using carburettors again in 1974 for the 2500TC, which had 99bhp, lower spec, and was cheaper than the 2.5PI. Then in 1975 the 2500S fully replaced the PI with a 106bhp carburettor engine, stiffer suspension and Stag alloys. This is the one to have.
