Trip in car, overlooking right seedy club! (4)
I believe the answer is:
dive
'seedy club' is the definition.
'trip in car overlooking right' is the wordplay.
'trip in car' becomes 'drive'.
'overlooking' is a deletion indicator.
'right' becomes 'r' (common abbreviation).
'drive' with 'r' taken away is 'DIVE'.
(Other definitions for dive that I've seen before include "Disreputable bar/club" , "Plunge into - disreputable club" , "Headlong plunge into water" , "Plunge; low bar" , "Jump into pool" .)
