Recommendations for (diesel) mechanics in Randburg area

[8BitLife]

Need to get my Isuzu serviced but would also like the guy to just give the engine a once-over and look for any bigger issues I might not be aware of. Just don't want to end up with someone who does a once-over and then makes up issues just to try and get as much money out of me as possible.

So if anybody knows a good (diesel) mechanic in the Randburg area you will trust with your life, please leave recommendations below. Someone you know who provides a decent, affordable service, you know?
