Marina's were reknowned for oil leaks, being gutless and the seats collapsing, I do recall landing in the back of mine as I was driving it . . . the car was a short term stop gap after a head on with a recovery truck in a mk4 Cortina . . . I went through a phase of mk3/4/5 cortinas back in the day, followed by about 6 Fiat 131's and an Argenta, then onto MK1 Cav's, Manta's, MK2 Cav's (8), Astra GTE's mk1 and 2 and so on, I'm a car feind and hence have a soft spot for lots of things, especially those I look back on with rose tinted glasses . . but the Marina  . . . definately not!
