Advice please! 1990 MX5
 

Hello
I am trying to sell my late Father's 1990 Eunos MX5 (152k miles) which has been in the garage unused for the past 3.5 years. It recently failed its MOT and I would need to spend around 380GBP to get it through. My gut feel is that I would be better off selling as is rather than spending the money to get it past its MOT but would welcome a more qualified opinion.
I should mention it is in good condition and has been well looked after.

Thanks in advance and let me know if you need more detail
