Thank you, Steve.
I'm looking at 2.0L automatics. Willing to consider 2.7L engines too. I've searched autotrader and found a few cars, as well as on Facebook marketplace. The latter actually has a lovely looking A5 but mileage is 110,000 for asking price of £8300. Valuation sites tell me that the car should be priced around £7000, if I remember correctly. It's a 2009 reg.
