3.0 litres are sought after under 100k miles, be lucky to get anything respectable for your budget

Yeah evo's are 316 brake, not 321 (din) and are obd2, so unless thrashed for a bit before rr will be down on that as they trim settings for economy.
3.0's always make their power if not more, and never much between them on the 1/4 mile.
Is a squarer engine too, better for high revs (safe to 8400).

As for mileage, well my box and diff are quiet, and as I said no oil use in 24k miles, not bad for a highly strung high mileage engine.

Soon be selling for an old sierra though lol.

Edit/ Pollocks - 3.0 is single vanos.
