Route from Cheshire to Lincoln?

[Synchromesh]

I need to go from Oulton Park to Lincoln next week. Sadly my UK geography knowledge ends once you get north of Birmingham.

I'll be in my mk1 MX5, so want to avoid big A-roads and stick to fun, scenic and quiet B-roads as much as I can. Nothing too badly surfaced though - it's a track car on silly coilovers.

I'll be slightly short of time so don't want to make the journey too much longer than it needs to be, either.

Does this look about right, or could it be improved on?

Thank you both!
