Any car of condition 4 and above is usually fine and has hardly any chance of engine problems
Even cars below 4 grade r good to go unless accidented
If engine has issues they are clearly mentioned on the left lower half of the auction sheet in Japanese under the comments section
So u cant tell unless u get the sheet translated
For verification of sheets older than 3 months u can whats app me the original sheet
We will try to dig it up from our database which has data upto cars auctioned in 2007
We can only verify 3 sheets per day
1 per person
for non clients,
Due to time constraints
So u can send the sheet @
0333-7777-945
&
We will reply iA
