FQ mean F******g Quick
FQs were bascially the ones sold properly through RallyArt so are fully UK models imported by Mitsi.
Top of my head the FQs were FQ300, FQ320, FQ340, and FQ400 producing 305ish 320 340 and 400 BHP. The 400 was faster round the Top Gear track than a Lambo.
There were other models like the GSR and some base models.
The 8 have the super AYC which is a shed load better on the track.
Nothing unusual. Make sure everything is working. AYC can be problematic on older ones but these are too new to be failing really. Breaks, Clutch, smoke and service history. The same as any high performance turbo car.
As for an FQ400 expect to pay an equal number of pounds and hens teeth. If you havent got that many hens teeth most traders will also accept rocking horse poo
