Two points to note...
1. Learn your gauge versus tank content...and get an mpg estimate as a back-up. The gauges on many cars fluctuate wildly on cornering.
2. The gauges may mist up/condensation on glass. No real worries as many do.
On my '93. 4/4 I drained and flushed the tank. I took the opportunity to check the gauge versus a known volume of petrol, adding 1 gal for a minimum reading with 1 gal left. This showed just touching the empty mark when stable and not fluctuating. Also for 2gal as an extra guide.
When you pick your car up spend a bit of time asking about the car and explain some characteristics of a Morgan.
Ask if they can show you the underside on a lift and explain the suspension and greasing as well. Be cheeky and ask if they will throw in a greasegun!
