Two minor things:
1) You can supply your own oil for the 1000 mile service
(must be 5W40 synthetic, as noted in other threads).
This will cut the cost of the oil in half (at least), plus it
fills the sump with oil you know you can purchase locally
when / if you need to top up.
2) Not a lawyer (not that there's anything wrong with that),
and certainly not a defender of Lotus and their logic, but
I wonder if one of the reasons for the ECU record is so
that they can get reimbursed from Toyota for engine
warranty claims? If the engine was not "abused",
according to the ECU record, then I would think that
Toyota might be expected to cover any warranty costs.
Just a thought.
