Lexus seriously needs to change a little bit to keep up with it's competition. Here's a suggestion, Lexus doesn't have to follow it, Lexus may not want to follow it. Introduce more models and increase model variants. For example:
RC 200t (coupe, convertible, 4 door coupe)
RC 300h (coupe, convertible, 4 door coupe) Market to techies, environmentalist, tree huggers, etc. BMW 4 series doesn't have a hybrid.
RC 300 awd (coupe, convertible, 4 door coupe)
RC 350 (coupe, convertible, 4 door coupe)
RC F (coupe, convertible, 4 door coupe) Competes with BMW M4
Bring back the SC
SC 350 (coupe, convertible, 4 door coupe)
SC 500h (coupe, convertible, 4 door coupe)
SC F (coupe, convertible, 4 door coupe) Competes with BMW M6
LC 500h (coupe, convertible, 4 door coupe)
LC 500 (coupe, convertible, 4 door coupe)
LC F (coupe, convertible, 4 door coupe) Competes with soon to arrive BMW M8
Bring back the LFA with a convertible limited to 500 units worldwide. The 2 door coupe has ran it's course.
This is just with entry, mid-level, flag ship coupe and an exotic. I'll have to create another post for sedans, SUV's and hybrids...
