Ah come on H "do the math" as the yanks say (I hate that!)
Option 1 -
Sell coupe (

)
rent/get mortgage for one hovel of a flat/miniscule house (

)
Get home and have to cook tea or eat whatever the mrs thinks of (

)
cycle to work (

)
Willy chinchilly is seen drinking fermented nut brew on park bench (

)
Option 2
Keep coupe ( :slayer: )
Live at home rent free (

)
spend money on Pc bits, car, food, and beer, glorious beer (

:slayer: :worship: )
Come home to real food cooked by the best chef in the world, dad ( :yum: )

Willy chinchilly leads a happy life, probably helped by the on tap raisins and ability to lick reproductory gland/testes whenever he wants (I've seen him do it)
So there you go! I'll move out probably just before my pensionable age
