Congrats on the purchase! You're gonna love it.Thanks for the advice - the seller did say on the phone that the coolant was looking a little low so he'd top it up. The car has been stood for a while so if the hoses are crap that could explain the low level.
The cambelt was last done in 2017 when the engine had some head work done, however I'm going to get it straight in for coolant flush, belts and general checkup as it's not worth the risk not to! Is the dephaser also a 5 year lifed item, or do they only need changing when they get noisy? Although the current one has been in since 2015, it's only done around 2k miles since then.
