Engine has given up after only 4 months of ownership. I only had a £500 warranty

Had lots over the years, shame it has to be the one that owes me the most...bit more crying
2 of the conrods have seized, so will need a rebuild.
Debating wether to sell it as it is, as someone in the know may be able to do a cheap fix?
Car is pretty standard tbh
Lots of history
Fully under sealed
Cat 1 Alarm
Of any interest to anyone?
