They were indeed a breath of fresh air! they saved BL (who were in serious trouble at the time) because they were honda powered, they of course, as you say were incredibly reliable... all 3 i owned never missed a beat and as you mentioned were quite quick too! the honda/BL partnership was a big success, running into the mid 90s. The last proper rover/honda was the 416 (re-badged concerto) i had one, it had 147,000 miles on it when i sold it, 72k when i got it... and in the 6 years i had it, it never let me down, it even still had its original clutch fitted too! the very last honda unit and gearbox in a rover was the 416 SLI auto (later the 45, tho when it became the 45, the honda unit was removed & became the same K Series as fitted with the rest of the range, with their own auto box) When BAE put up rover for sale i believe honda put a bid in as they had a 20% stake in the company at the time... shockingly after all they had done in the past and put in to the success of rover they were turned down in favour for BMW, not long after this. honda sold there stake and the partnership ended.... BMW only bought the group for land rover which they raped for the 4x4 technology, they run the rover side of it down and sold it for a £1 to the Phoneix group... the rest we know... such a shame, if honda had bought rover, it would still be around today making great reliable cars in britain.....
Here is the rover 416 i had.....
