The pre-facelift 75 is still an achingly pretty thing. I would love a 2.5 KV6 example. Saloon or Tourer, not fussy...

I had a V6 ZT and don't rate that engine at all. Sounds nice but slow tbh.

That engine is much better suited to the ZS. The ZT is a bit of a lard arse.

I can imagine in a smaller, lighter car it would be good.

[confused_buyer]

The problem with the KV6 is about 95% of them now have broken VIS valves - either the one or both of the motors are not working or all the valves have broken. This means most of them have about 120bhp.

Therefore, people drive them and think "this is a bit slow" because they are, but they're not meant to be like that.

Also, regarding the post above about the diesel having no go below 2100rpm it should be quite progressive so if it is completely flat below 2000rpm the MAF is knackered.

I had the valves replaced on mine and it was still slow.

Suspected as much but in fairness, the former one that didn't have the light switch effect at that rpm, was hardly more sprightly down low - it's a lardy old bus for the engine. Would love to do an 'Alpina D3' on that M47R...

Ok, well it should not have been. Perhaps the replacements were faulty or improperly fitted? More likely the manifold itself was knackered too. this badly affects the throttle butterflies. It was not until I had mine REALLY fixed that I realised what I had been missing all that time. Especially above 4K rpm.
They were no M3 though - but then again they were nowhere near M3 money.

I guess it depends what you are comparing it to performance wise. But you can't expect too much with that amount of power in a big heavy barge like a ZT.

I loved my bargain basement 75 2.0 V6 auto. FSH and owned by one elderly couple who used it to potter about town.

Well, I loved it for three months. Then a bit of the rear suspension decided to snap while I was driving it and I had to scrap it due to the high repair cost:car value ratio.

Shame, it was a comfy old thing with lots of character.

[RoverP6B]

I've spent far more on my E39s than their resale value. There's no "have to" where scrapping otherwise serviceable cars is concerned. It all depends how much you like the cars. I love my E39s even though they're a total pain in the arse at times.

As for the KV6's various problems, manifolds etc, could one not just get the requisite parts replaced in metal? Even if nobody stocks said parts, it can't be that hard to get a custom set of manifolds run up.

A few people have just gut the intake manifold completely to remove the flaps, etc.

[itcaptainslow]

You can't "gut" a KV6 inlet as far as I'm aware. I think you're thinking of the BMW diesel-but I don't think the unit fitted to the 75 has swirl flaps in the manifold.

Yes, but this makes the KV6 rather gutless low down. The whole idea of the design of the inlet manifold design was to enhance torque at the bottom end using the longer inlet tracts and then to add the short tracts as well at high RPM to boost the top end. ( I think that's the right way round!)

You can gut them, but getting the thing apart is damn difficult and getting it back together again without any air leaks even harder.

[Rafeabrook]

The bloke running this *car lot* for the blue MG (near Maulden) is not someone I would buy a car from

I went to look at the ST220 he had in there and he couldn't have been more rude or less helpful

He seems to only want to deal with Trade people willing to pay Consumer prices. Advertised the car at £2695, then after I enquired over the phone it magically went up £300 the next day when I viewed!

Any potential purchasers have been forewarned!

I do like a stealthy estate, but not an MG one. I just don't get the appeal at all.

As for the diesel - never in a million years, what a hateful turd of a machine, someone called it achingly pretty earlier on in the thread - are you mental, Sir? I know tastes are subjective, but my word it's a sad looking thing.

I'd rather spend a bit more for a Saab or Volvo, or even look at the cheapo Passats kicking around, personally.

Well, Saabs and Volvos from the era are nowhere near as nice to drive. A Passat... What on earth are you on?

[RoverP6B]

The Passat was another one with a madcap eight-cylinder variant that sold in tiny numbers, but it was basically half a Veyron engine...
