This is probably one of the complicated logo you will come across as this is combined logo of TWO COMPANIES. Details are mentioned below;
1. Brisbane Autocare - This is one stop mechanical workshop for all cars
2. DTSQ- the Company which does Wheelchair accessible vehicle modifications 

All NEW design for Brisbane Autoacre are welcome but i do not want to change too much (different font style can be used to match new Brisbane Autocare font ) . Then put both logos together just separating  with either vertical or horizontal line .This can be combined logo which will be easy to use on letterheads, Cards or any other office material . I would also like to have separate logos with similar font style so they can be used together where needed. I will upload both my logos as well as BOSCH logo which MUST be used on our letterheads. I would like to use combination of BLUE &amp; SILVER , BLUE ,RED &amp; GREY or BLUE &amp; White. Please try to keep blue as close as possible to match blue used in BOSCH . 

All new ideas are also Welcome as long DTSQ shows something related to wheelchair 

Agus is very creative and response is prompt. She made exact logo I wanted by keeping the old brand with new creative look. I would definitely use her services in the future.
