Just a thought. Keep an eye open for a well looked after GQ with the 4.2. Should fit your budget.
It's a bit like driving a block of flats from inside a Spinal Tap amplifier, turned up to 11, but they are an honest old workhorse.
Do all you require and then some.
There's any number of ex GQ owners on the forum who'd give an arm to have it back, so they reckon.
