Hi - welcome.
We've seen your car on ebay.
1. how do you know you've "blown the bottom end"? symptoms?
2. how do you know you blew the turbo?
these engines are bloomin tough
JJ
bottom end symptoms, knocking from underneath the car when the engine is running due to running low on oil.
blown turbo, lack of power, black smoke out of the exhaust if the turbo oil seals have failed, which could contribute to bottom end knock
the engines are only as tough as you say they are IF they have been looked after or the ancillaries attached to it have been looked after.
as to the value, id say at most scrap value (£2-500) as is.
it'll be worth more if you break it for parts.... i call dibs on the heated seats and relay
