It's just my two pence worth but I have a 95 4 wd TD and while the performance is leisurely it's adaqute but if you need a performance bus then a young t5/6 is for you .
As a general rule we don't overtake in the bus , it's just not good at it !
Having said all that I've done some " performance upgrades " thanks to rustyp on here or at the porting shed on Facebook and I must say it's made an improvement to the overall get up and go
